Surface tension tanks exploit the liquid surface in transport and gas–liquid separation to provide gas-free propellant for thruster. High efficiency of deflectors can ensure relocation microgravity environment within a short period time, which is helpful providing propellant. This paper explores through drop tower experiments numerical simulations with volume fluid method. The experimental resu...

The sloshing phenomenon is an important field of fluid dynamics in liquid storage tanks under earthquake excitation. When the frequency gets close to tank’s natural frequency, resulting resonance could lead instability and even damage structures, followed by catastrophic economic losses environmental damages. As passive control devices, baffles are a place for energy dissipation. This study use...

The possibility of employing internal wall as mass absorber in rectangular water storage tanks subjected to harmonic ground motion excitation is investigated in this paper. Internal walls are used in these tanks usually for service performance purposes, which could be used as mass absorber to control seismic demand on tank's exterior walls. Derivation of the response of the coupled system inclu...

Abstract Fuel sloshing-induced damping is currently being studied extensively within the EU-funded SLOWD project as a means of passively reducing dynamic loads in aircraft wings. It interest to be able determine which parameters have greatest influence on added from sloshing motion. An uncertainty measured force has been observed when multiple consecutive and identical oscillation cycles are co...
